Yes you are understanding correct, I meant the gradient of the characteristic. And this was exactly my question in the first place. I am wondering why I need so much volume spacers, so that the X2 feels somehow stable, because I am NOT riding extreme trails with huge jumps.
So I guess I am alone with this setup

But I think, too, that it is pretty strange to use 3 out of 4 possible volume spacer. I am not that heavy either. So big mystery to me, but whatever works. After all the shock feels great. It is sensitive and responsive with great feedback. So everything I expect from a shock.
